A library of heterocyclic products with a wide variety of organic residues is produced via a four-component reaction of α,β-unsaturated aldehydes, primary amines, carbon monoxide, and ethylene using a multi-reactor station with an array of 96 autoclaves employing the same high-pressure reaction conditions for all catalytic reactions. In the presence of Ru3(CO)12 as a precatalyst, mixtures of chiral γ-lactams and 2,3-disubstituted pyrroles are obtained. This combinatorial approach also enables us for the first time to set up rules relating to the effects of specific substituents in the substrates on the outcome of the respective catalytic reaction.
通过四个反应组分的反应,即α,β-不饱和醛、伯胺、一氧化碳和乙烯,在一组96个高压釜的多反应器站中,采用相同的催化反应高压条件,生成了一系列含有多种有机残基的杂环产品库。在Ru3(CO)12作为预催化剂的存在下,得到了手性的γ-内酰胺和2,3-二取代吡咯的混合物。这种组合方法还使我们首次能够建立特定取代基对各自催化反应结果影响的规则。
